Surface characterization of plasma treated carbon fibers and adhesion to polyethersulfone
(Virginia Tech, 1992-08-05)
A series of RF plasmas was chosen to modify the surface chemical composition of Hercules IM7 carbon fibers. A two-liquid tensiometric method was used to determine the surface energy parameters y(ds) and I(psf) of the fibers. ...
Effect of interfacial thermal conductance and fiber orientation on the thermal diffusivity/conductivity of unidirectional fiber-reinforced ceramic matrix composites
(Virginia Tech, 1992-02-06)
The role of an interfacial barrier at the fiber-matrix interface in the heat conduction behavior of an uniaxial silicon carbide fiber-reinforced reaction-bonded silicon nitride and the effect of fiber orientation on the ...
X-ray diffraction from point-like imperfection
(Virginia Tech, 1992-01-15)
Displacement fields from point-like defects are investigated by x-ray diffraction. The atomic volume changes in the interstitial compounds using crystallographic information has been found to correlate with the size of ...
Determination of thermal strains in the neighborhood of a bimaterial interface
(Virginia Tech, 1992)
The single fiber pull-out test: a study of fiber/matrix interactions
(Virginia Tech, 1992-05-04)
Studies on the reactivity of thiophosphate/thiophosphinate and ethyl xanthate with precious metals
(Virginia Tech, 1992-12-05)
Adsorption mechanisms of modified thiol collectors on gold, silver, and gold-silver alloys have been studied and compared with those of ethyl xanthate (EX). The modified thiol collectors include dicresyl monothiophosphate ...
Cellulose-based fibers from liquid crystalline solutions
(Virginia Tech, 1992-02-05)
Processing - structure - property interrelationships of ferroelectric thin films with emphasis on formation kinetics
(Virginia Tech, 1992-07-05)
Lead zirconate titanate (PZT) is a ferroelectric material which has many interesting properties. Recently, PZT thin films have been considered as one of the most promising materials for the application of nonvolatile ...
Fundamental studies of the tribological behavior of thin polymeric coatings in fretting contact using infrared and photo/video techniques
(Virginia Tech, 1992-01-15)
Direct measurements of surface temperatures produced during fretting contact are an unknown area in the discipline of tribology; in addition, the possible effects of such temperatures on the behavior of protective anti-fretting ...
Poly(2-alkyl-2-oxazoline) containing multiphase systems
(Virginia Tech, 1992-05-01)
This research is focused on the polymerization of 2-alkyl-2-oxazoline homopolymers and 2-alkyl-2-oxazoline containing copolymers with well-defined structures. In addition, the potential of selected materials as polymer ...
